5.3 Processing
1. Red laser light stimulates the sensitive surface
of the imaging plate.
2. Imaging plate glows blue light in relation to the
amount of X-ray information stored to the plate.
3. Glowing blue light is optically collected pixel by
pixel (line by line) and measured with extremely
sensitive photo-detector.
4. Digital image is formed from the measured light
intensity variation.
After stimulating, imaging plate is exposed to
bright light, which clears the remaining image
information from the plate. The imaging plate is
dropped out of the unit.
X-ray exposures and processing are not aging the
imaging plate, so it is re-usable hundreds of times.
In practice, mechanical wearing limits the service
life of the plate.
